[PATCH 5.14 078/100] thermal/drivers/rcar_gen3_thermal: Store TSC id as unsigned int

From: Greg Kroah-Hartman
Date: Fri Sep 24 2021 - 09:03:42 EST


From: Niklas Söderlund <niklas.soderlund+renesas@xxxxxxxxxxxx>

[ Upstream commit d3a2328e741bf6e9e6bda750e0a63832fa365a74 ]

The TSC id and number of TSC ids should be stored as unsigned int as
they can't be negative. Fix the datatype of the loop counter 'i' and
rcar_gen3_thermal_tsc.id to reflect this.
